look up any word, like dirty sanchez:
 
1.
To repeatedly fire a .50 caliber weapon (such as the .500s&w, .50BMG, 50-70, .50AE etc) in the air several times to wake somebody up or get their attention much like Richard Machowicz when he fires his .50 caliber weapons on the badass tv show "Future Weapons".
*Kyle and Joe at the shooting range*
Joe: kyle!
kyle: ...........
Joe: KYLE!!!
kyle:........
Joe: *fires desert eagle 4 times*
kyle: ahhh!! what is it!!
Joe: apparently you needed a mack wake up to get your attention.
